Custom case that I had made a few years ago and only used twice. Used it to hold a delicate tennis racquet stringing machine. Dimensions are 44in X 20.5in X 24in. It is the speedster option that transforms the case into a self contained transport case with little effort. Also includes telescopic handle. Mechanism is fully enclosed within case to avoid damage in transit. Heavy duty built-in wheels are durable, nonskid rubber and include steel ball bearings for smooth operation. Also has two durable Hasp locks. Also comes with a custom carpeted foam interior and lid. Entire unit is in near brand new condition, paid nearly $1,000 for it brand new. Would be excellent for musical instruments or delicate electronic devices. Asking for $700 or best offer. Would be cheaper/easier to pick up in person. I live in Southern California. *Note: Photo is a stock photo of very similar case. If you want more pictures, please let me know and I will take some.
